On my laptop I’m running Ubuntu Linux 8.04 with
XFCE 4.6 and it works great. But (Isn’t there always a
‘but’?) every once in a while I killed my Xsession with some type of key
combination. The standard combination for this is Ctrl-Alt-Backspace so I
switched that off in the file /etc/X11/xorg.conf'. I added the ServerFlags` section, like this.
Section "ServerFlags"
Option "DontZap" "on"
EndSection
After restarting I tried the dreadful Ctrl-Alt-Backspace and I thought that
‘Bob’s your uncle’.
How disappointed I would be. I started work again and suddenly my X session
was killed again, and again and again. And then I saw it, I was not pushing
the Ctrl-Alt-Backspace combo, but I tried to insert text with Shift-Insert
and accidentally hit Shift-Backspace. Now I had a point to start my search.
Googling and file digging revealed that my keyboard was set to PC-101 and that it should be PC-105. Strange, but solvable. I switched the keyboard in the XFCE settings panel and my problem was solved. It can also be solved by adding
setxkbmap -model pc105 -layout us -variant basic
to the startup script for your window manager.
But, of course, I could not just accept the solution and leave it to that.
The problem turned out to be Compiz, the
fantastic OpenGL accelerated desktop. This has a feature that the
Shift-Backspace turns out to be for debugging purposes.
Yeah, right! We already had Ctrl-Alt-Backspace for that, right!
